Description

Technical Field

[0001] The utility model relates to the technical field of labeling plastic packages for cigarette carton delivery, and in particular to a side labeling device for plastic packages for cigarette carton delivery. Background Art

[0002] In commercial tobacco distribution centers, cigarette distributors distribute cigarette cartons of different brands and quantities according to the order requirements of cigarette retailers, and stack and organize the distributed cigarette cartons into plastic packages. After the cigarette cartons are packaged, labels with distribution information need to be affixed to the outer packaging of the plastic packages to facilitate classified distribution by distribution personnel. In the prior art, it is generally adopted to set a labeling device above the conveyor belt that transports the plastic packages of cigarette cartons. During the transportation of the plastic packages of cigarette cartons, the labeling device extends downward to label the upper surface of the plastic packages of cigarette cartons. However, due to the different numbers of cigarettes packed in the plastic packages for cigarette delivery, and the different brands of cigarettes having different outer packaging specifications, for example, the size and thickness of the outer packaging of some hard boxes, soft boxes, slim and medium cigarettes are also different, the cigarettes on the top layer often appear uneven after stacking, causing the upper surface of the plastic package for cigarette delivery to be uneven. When labeling the plastic packages with uneven upper surfaces using the existing labeling methods, it is easy for the label to not completely fit with the upper surface of the plastic package for cigarette delivery, resulting in false labeling, which causes the label to easily fall off or be lost during subsequent delivery, resulting in inaccurate delivery.

DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0018] Please see Figure 1 and Figure 2 The embodiment of the utility model provides a lateral labeling device for plastic packs of cigarette cartons, comprising a conveying device 1 for conveying plastic packs of cigarette cartons, a label printer 2 and a label pushing mechanism 3, wherein the conveying device 1 is a belt conveyor or a roller conveyor, and the label printer 2 is arranged on one side of the conveying device 1 along its conveying direction, and the label pushing mechanism 3 is transversely arranged at the label outlet 21 of the label printer 2, and can move in parallel to the conveying surface direction of the conveying device 1 along the label outlet 21 of the label printer 2, and the extension direction of the label pushing mechanism 3 is perpendicular to the conveying direction of the conveying device 1. When labeling, the conveying device 1 conveys the plastic packs of cigarette cartons to be labeled through the label printer 2 in sequence, and the label printer 2 prints the labels corresponding to the plastic packs of cigarette cartons. When the plastic packs of cigarette cartons pass through the label printer 2, the label pushing mechanism 3 pushes the labels printed by the label printer 2 to the plastic packs of cigarette cartons, so that the labels are attached to the side walls of the plastic packs of cigarette cartons to complete the labeling.

[0019] Specifically, the label pushing mechanism 3 includes a positioning seat 31, a labeling push rod 32 and a telescopic arm 33. The positioning seat 31 is installed on the side of the label outlet 21 of the label printer 2 away from the conveying device 1. A penetrating slide hole 34 is opened on the positioning seat 31 in parallel with the direction of the conveying device 1. The labeling push rod 32 is inserted into the slide hole 34 and can freely telescope and slide along the slide hole 34 toward the direction of the conveying device 1. The telescopic direction of the labeling push rod 32 is perpendicular to the conveying direction of the conveying device 1. The labeling push rod 32 is directed toward the conveying device 1. The end is provided with a label adsorption head 35, the telescopic arm 33 is installed on one side of the positioning seat 31, the telescopic arm 33 and the labeling push rod 32 are parallel to each other, the telescopic end of the telescopic arm 33 is connected to one end of the labeling push rod 32, the telescopic arm 33 is a cylinder, which is connected to an external air compressor, and compressed air is provided by the air compressor, and the telescopic arm 33 is controlled by a solenoid valve to work, so that the telescopic arm 33 can push the labeling push rod 32 to move telescopically along the positioning seat 31 toward the conveying device 1. After the labeling push rod 32 is retracted, the label adsorption head 35 is located at the label printing The label outlet 21 of the label printer 2 is away from the side of the conveying device 1 and is aligned with the label outlet 21 of the label printer 2. The inner cavity of the label adsorption head 35 is a negative pressure cavity. The side of the label adsorption head 35 facing the conveying device 1 is an adsorption surface. A suction hole 36 connected to the negative pressure cavity is provided on the adsorption surface. The negative pressure cavity is connected to an external negative pressure device, for example, a negative pressure machine or a negative pressure pump. The negative pressure cavity is sucked by the negative pressure device to generate suction in the suction hole 36. After the label printer 2 prints out a label, the front of the label faces the adsorption surface of the label adsorption head 35. The back of the label faces the direction of the conveying device 1, and the back of the label has adhesive. When the telescopic arm 33 drives the labeling push rod 32 to move in the direction of the conveying device 1, the adsorption surface of the label adsorption head 35 contacts the label printed by the label printer, and the label is adsorbed under the adsorption force of the suction hole 36. The labeling push rod 32 pushes the label adsorption head 35 to pass the label printer 2 and continue to move in the direction of the conveying device 1 until the label is pushed onto the side wall of the plastic package of cigarette delivery conveyed on the conveying device 1, so that the back of the label is adhered to the side wall of the plastic package of cigarette delivery, and the labeling is completed.

[0020] Please continue to see Figure 1 and Figure 2Furthermore, during the labeling process, since the cigarette delivery plastic package is subjected to lateral force, the labeling push rod 32 is likely to push the cigarette delivery plastic package to the outside of the conveying device 1 when pushing the label. In order to prevent the cigarette delivery plastic package from deviating, a side block auxiliary device 4 is provided on the other side of the conveying device 1 along its conveying direction. The side block auxiliary device 4 includes a baffle 41 and a support frame 42. The support frame 42 is provided on the side wall of the conveying device 1. The baffle 41 is vertically provided on the side of the support frame 42 facing the label pushing mechanism 3, and is connected to the label pushing mechanism 3. The label pushing mechanism 3 is directly opposite to the conveying device 1, and the cigarette delivery plastic package conveyed by the conveying device 1 passes between the baffle 41 and the label pushing mechanism 3. When labeling, the label pushing mechanism 3 will generate a thrust on the labeling side of the cigarette delivery plastic package, pushing the cigarette delivery plastic package to the side of the baffle 41. The baffle 41 provides lateral support for the cigarette delivery plastic package, which can prevent the cigarette delivery plastic package from deviating to the outside of the conveying device 1, so that the labeling push rod 32 can apply force to the side wall of the cigarette delivery plastic package, so that the label is tightly attached to the cigarette delivery plastic package to prevent the label from falling off.

[0021] The support frame 42 is provided with a sliding sleeve 43 in the horizontal direction, and the axial direction of the sliding sleeve 43 faces the label pushing mechanism 3. A sliding rod 44 is provided in the horizontal direction between the baffle plate 41 and the support frame 42. One end of the sliding rod 44 is connected to the baffle plate 41, and the other end passes through the sliding sleeve 43 and can slide freely along the sliding sleeve 43. The baffle plate 41 is supported by the sliding rod 44 and is suspended at the edge above the conveying surface of the conveying device 1, facing the label pushing mechanism 3, and can telescopically move along the sliding sleeve 43 toward the label pushing mechanism 3. In order to prevent the sliding rod 44 from disengaging from the sliding sleeve 43, a limit stopper 45 is provided at the end of the sliding rod 44 passing through the sliding sleeve 43. The outer diameter of the limit stopper 45 is larger than the aperture of the sliding sleeve 43. The sliding rod 44 is limited by the limit stopper 45 to prevent the sliding rod 44 from disengaging from the sliding sleeve 43. A spring 46 is sleeved on the sliding rod 44, and one end of the spring 46 abuts against the baffle plate 41, and the other end abuts against the support frame 42. On the support frame 42, the spring 46 is a compression spring 46, which pushes the baffle 41 toward the conveying surface of the conveyor 1. When labeling is performed, the cigarette delivery plastic package on the conveying surface of the conveyor 1 will be squeezed toward the baffle 41 after being pushed by the label pushing mechanism 3. When the squeezing force of the cigarette delivery plastic package on the baffle 41 is greater than the supporting force of the spring 46, the baffle 41 can shrink and move along the sliding sleeve 43 toward the support frame 42 to buffer the squeezing force of the cigarette delivery plastic package, thereby preventing the cigarette delivery plastic package from being subjected to excessive thrust from the label pushing mechanism 3, causing deformation of the outer packaging of the cigarette. The baffle 41 will compress the spring 46 during the shrinking movement, causing the spring 46 to deform. When the label pushing mechanism 3 completes the labeling action and returns to the starting position, the baffle 41 is reset under the reaction force of the spring 46, and pushes the cigarette delivery plastic package to reset, so that the cigarette delivery plastic package moves to the middle of the conveyor 1 again.

[0022] Furthermore, the end surface of the baffle 41 that contacts the plastic pack for delivering cigarettes is a smooth surface, so that when the plastic pack for delivering cigarettes contacts the baffle 41 , the friction between them can be reduced.

[0023] Furthermore, both ends of the baffle 41 facing the conveying direction of the conveyor 1 are bent toward the outside of the conveyor 1 to form an arc-shaped plate, which can play a guiding role and prevent the end of the baffle 41 from scraping the cigarette delivery plastic package, so that the cigarette delivery plastic package can be smoothly conveyed on the conveyor 1.

[0024] Please continue to see Figure 1 and Figure 2Furthermore, the conveying device 1 includes a bracket 11, a conveying roller 12 and a driving motor 13. The bracket 11 is arranged in parallel, and there are several conveying rollers 12, which are arranged at intervals along the length direction of the bracket 11. A transmission belt 14 that is linked to each other is provided between two adjacent conveying rollers 12. The driving motor 13 is arranged at one end of the bracket 11 and is connected to the axis of one of the conveying rollers 12, and drives the conveying roller 12 to rotate on the bracket 11. Several of the conveying rollers 12 are linked by the transmission belt 14 to rotate synchronously in the same direction for conveying plastic packages of cigarette cartons. The label printer 2 and the side barrier auxiliary device 4 are relatively arranged on both sides of the bracket 11. The label pushing mechanism 3 can move in parallel and telescopically along the label outlet 21 of the label printer 2 toward the conveying surface direction of the conveying roller 12, so as to push the label output by the label printer 2 to the plastic package of cigarette cartons conveyed on the conveying roller 12, so that the label is adhered to the side wall of the plastic package of cigarette cartons.

[0025] During the labeling process, the side barrier auxiliary device 4 provides lateral support force to the labeled cigarette delivery plastic package to prevent the cigarette delivery plastic package from shifting to the outside of the bracket 11. It also facilitates the label pushing mechanism 3 to apply force to the side wall of the cigarette delivery plastic package to make the label stick tightly to the cigarette delivery plastic package to avoid the label falling off.

[0026] Please see Figure 1 or Figure 2 In another preferred embodiment, anti-slip rings 15 for increasing friction are respectively provided on the plurality of conveying rollers 12 in the labeling area corresponding to the label pushing mechanism 3. The anti-slip rings 15 are preferably rubber rings, which are tightly mounted on the conveying rollers 12 and are spaced apart along the axial direction of the conveying rollers 12. The anti-slip rings 15 rotate synchronously with the conveying rollers 12. When the cigarette delivery plastic package is conveyed to the labeling area, the anti-slip rings 15 contact the bottom of the cigarette delivery plastic package. The anti-slip rings 15 are used to increase the friction between the conveying rollers 12 and the cigarette delivery plastic package, which can reduce the deviation of the cigarette delivery plastic package toward the outside of the bracket 11 during the labeling process, so that the label pushing mechanism 3 can apply force to the side wall of the cigarette delivery plastic package.

[0027] The anti-slip ring 15 in this embodiment and the above-mentioned side stop auxiliary device 4 can be implemented separately or in combination, and both can prevent the cigarette delivery plastic package from deviating to the outside of the bracket 11 during the labeling process.

[0028] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
